The interstitium is necessarily involved in all intrarenal exchange processes since the reabsorption and secretion of fluid and solutes implicates a transit across the interstitial compartment. The fibroblasts in the interstitium provide the 'skeleton' of the tissue and maintain the three-dimensional architecture of the tissue. continuant Homo sapiens Homo sapiens kidney interstitial fibroblast kidney stroma interstitial tissue part_of part of part of composed primarily of contributes to morphology of
